Pesticide synergist and preparation method thereof

By combining a pesticide synergist composed of potassium oleate, dipotassium hydrogen phosphate, and 2-hydroxy-4-methylvaleric acid with chemical pesticides, the problems of limited synergistic effect and unsatisfactory environmental compatibility in existing technologies have been solved. This has achieved a significant reduction in pesticide usage while maintaining high efficacy, which meets the requirements of green agriculture.

AI Technical Summary

Technical Problem

Existing pesticide synergists have limited synergistic effects, high costs, and poor environmental compatibility when controlling fungal diseases, making it difficult to maintain high efficacy while reducing the amount of chemical pesticides used.

Method used

A pesticide synergist with potassium oleate, dipotassium hydrogen phosphate and 2-hydroxy-4-methylvaleric acid as the main components is mixed and stirred to form a homogeneous solution. When used in combination with chemical pesticides, it significantly improves the control effect of pesticides.

Benefits of technology

It has achieved a 50%-80% reduction in the use of chemical pesticides, while maintaining or improving the control effect, reducing pesticide residues and environmental risks, and meeting the needs of green agricultural development.

Abstract

The invention discloses a pesticide synergist and a preparation method thereof. The synergist is prepared from 7-9 parts of potassium oleate, 1-2 parts of dipotassium phosphate and 1-2 parts of 2-hydroxy-4-methylvaleric acid according to a specific mass ratio. The preparation method comprises the following steps: stirring and mixing the components at normal temperature until the components are completely dissolved to form a homogeneous solution. The synergist disclosed by the invention can be compounded with chemical pesticides such as triadimefon, carbendazim and azoxystrobin for use, and by enhancing the attachment and permeation of the pesticides on the surfaces of plants and the binding efficiency of the pesticides and pathogenic bacteria targets, the control effect of 90% or above can be still maintained under the condition that the dosage of the chemical pesticides is reduced by 50%-80%, and pesticide residues and environmental risks are remarkably reduced. The invention has the advantages of easily available raw materials, simple process and low cost, is suitable for large-scale production, and has important significance for realizing agricultural pesticide reduction and synergism and sustainable development.
